Abstract: PANT HANGER WITH INTERNAL SPRING              ABSTRACT OF THE DISCLOSURE         The disclosed garment hanger has an elongated, molded plastic body with clamps at each end.  Each clamp has a pair of spaced legs interconnected by an integral web between its ends which holds the legs substantially spaced from each other.

Abstract: 81154 - Formax MOVABLE GRID STACKER FOR A FOOD SLICING MACHINE           Abstract of the Disclosure This invention is a stacker for a food loaf slicing machine of the kind in which a food loaf is advanced into a slicing station where slices of generally uniform thickness are cyclically sliced from the end of the loaf.  The stacker includes first and second stack supports which are positionable to receive slices as they are cut off the loaf.          When one stack support has received a complete stack that support is moved to a displaced discharge position and the other stack support immediately moves into an initial slice receiving position immediately adjacent the slicing station, where it can receive a first food loaf slice as cut with essentially no free fall.  The stack support is then displaced downwardly approximately one additional slice thickness for each successive slice received, so that each food loaf slice is added to the stack with no free fall.  The stack supports transfer the stack to the discharge position without any free fall; continuous support is provided throughout all stack formation and transfer operations.

Abstract: "HIGH EFFICIENCY CONTINUOUS SEPARATION PROCESS"                 ABSTRACT         A process for separating an extract component from a raffinate component contained in a feed mixture. A unidirectional fluid flow system is maintained through a series of separating units through which the components travel at different rates. A component concentration distribution is established within the system of units and divided into specific zones. Feed and dis-placement fluid are passed into the inlets of two of the units and extract and raffinate are taken as the entire streams from outlets. of two of the units all at appropriate points on the component concentration distribution. Other inlets and outlets of the various units lying in the same zone are interconnected.  At the appropriate times the inlets and outlets are shifted so as to simulate movement of the units in a direction co-current with the fluid flow and thereby enable the inlets and outlets to continually lie in the appropriate zones.  Zones may be combined as zone pairs, each such pair thereupon being considered a single continuous zone. For each such combination, the number of separating units required may be reduced by one. Such combinations would be warranted in instances where a lesser degree of purity, concentration or recovery of a given component would be acceptable.
